Reported using DrKonqi
crashes in nvidias blob, glDeleteTextures(), causing or caused by a mem corruption - 260 is still the beta driver? - is this reproducible? (if you do exact the same, the exact smae happens again?) -> to workaround the issue, suspend compositing (SHIFT+ALT+F12) before changing screen/resolution (plain resolution changes via xrandr should be ok, afaics) toggle again to resume compositing
260.19.04 is a beta driver. Sorry, I can't reproduce at will... I switch screens and resolution 2-3 (or more) times a day, and have been running that driver for a week or two. Thanks for the workaround. At this point I won't use it so as to catch more data.
